We show that invertible transformations of dynamical variables can change
the number of dynamical degrees of freedom. Moreover, even in cases when the number of dynamical degrees of freedom remains unchanged, the resulting dynamics can be essentiallydifferent from the one of the system prior to transformation. After giving concreteexamples in point particle cases, we discuss changes in dynamics due to invertible disformal transformations of the metric in gravitational theories.
